VCR repair
Hi,
I rescued a couple of "decent" (?) VCRs -- both of which need some work. They a JVC BR-S378U Sony SLV-R1000 I haven't spent much time on either of them. The purpose of this post is to get advice as to which might be best to start looking at. And, to see if anyone has pointers to service manuals on either of them. So, anyone with firsthand experience with either of these? Thanks! --don |

They a JVC BR-S378U Sony SLV-R1000 Guess it depends on what is wrong with each of them but as an opinion, the JVC looks similar to another model I've worked on in the past (hrs9800) and were probably the last "built like a tank" models they produced. Besides like the belt/idler problems, those had a poorly designed power supply, which is right behind when the line cord is, really crammed in there, it overheats and takes out the STK module on the board. It's somewhat easy to figure out because the STK supplies the +5 and +12 (there might be a 3rd section for +18 or so), but they do legend the board. Keep in mind, if it's anything else, it's probably not worth proceeding, both of those appear to use uncommon video head assemblies, four or six head designs with flying-erase. Really doubt either company has them anymore and really doubtful there were any knock-offs made from the chinese. Probably cost a small fortune even when they were available. -bruce |
